Effect of endoparasites occurrence in sows from intensive production system

Abstract

The goal of this study was to assess the effect of farm size (FS) and farrowing order (FO) on the occurrence of endoparasites eggs in commercial sows housed in maternity and gestation areas during the period from May to July 2014. Forty-three piglet production units were classified by FS: small (100 to 250 sows), medium (251 to 510 sows), large (511 to 1,000 sows) and very large (more than 1,000 sows). Sows were classified by FO: up to two, three to five or more than five parturitions. Faecal samples were processed using the simple flotation technique in a hypersaturated salt solution (30-35% NaCl). The results revealed that the overall prevalence of gastrointestinal endoparasites obtained in this study was 12.47%, in that 4.64% were positive for Ascaris suum, 0.56% for Trichuris suis and 8.27% for coccidia oocysts. The prevalence of endoparasites obtained for small and medium size farm, and for large and very large farm was 34.58% and 15.52%, respectively. In conclusion, the study shows that more than half of the farms were positive for A. suum and coccidia oocysts, but mainly for younger females. In general, sows with up to two parturitions and small farms showed a higher endoparasites percentage.

The impact of certain flavourings and preservatives on the survivability of eggs of Ascaris suum and Trichuris suis

“…Today, most farmers use synthetic broad-spectrum anthelmintic preparations against ascariasis and trichuriasis of pigs, though some of them have notable side effects (Jakobsen et al, 2019;Vandekerckhove et al, 2019). At the same time, repeated infection poses a threat of development of nematodes' resistance to antiparasitic preparations (Ceballos et al, 2019;de Oliveira et al, 2019;Palma et al, 2020). Therefore, alternative veterinary and medical preparations with anthelmintic activity are now being searched for all around the world (Boyko & Brygadyrenko, 2019с;Palchykov et al, 2019).…”
